ATTACHMENT FOR THRASHING'MACHINES AND CLOVER. l-IULLER-Sj.

Application filed May 29,

T 0 all whom it may concern:

Be it known that WILLIAM E., TOLER,

a citizen of the United States of America,

residing at Pawnee in the county of Pawnee and State of ()klahoma, has invented certain new and useful Improvements in Attachments for Thrashing Machines and Clover Hullers, of which the following is a specification.

This invention relates'to an improved system of handling straw, chaff, tailings and refuse forthrashing separatorsv or machines, clover hullers, and other like machinery.

The principal Object of the above entitled invention is to provide in a single machine a mechanism which will reduce to a minimum the power usually required by larger machines doing the same work by the reduction of frictiondue to the elimination of a number of bearings, drive beltsand other mechanical parts usually associated with such machines.

A further feature is the production of a machine designed to more thoroughly clean out and thresh the material and to increase the capacity or output of the machine without a corresponding increase in the size of the machine, and with the use of a smaller and less powerful power plant.

Other objects and advantages will appear to those familiar with the art to which this invention relates.

In the accompanying drawings,

Figure 1 is a side elevation of the right hand side of a thresher showing the straw and chaff elevator and a portion of the stacker tube in section;

Figure 2 is a view similar to Figure 1, but illustrating certain of the other c0nveyor tubes;

Figure 3 is a side elevation of the left hand side of a thresher showing the arrangement of the tailings elevator tube;

Figure 4 is also a side elevation of the left hand side of the thresher but showing the blower, air conducting tube and cleaning riddles;

Figure 5 is a transverse section thru the separator at the forward end thereof and illustrating the thrashin cylinder and the blower and suction fan 0 ambers.

Figure 6 is a transverse vertical sectional view thru the separator and the air chamber,

Figure 7 is a transverse vertical sectional 1922. Serial No. 564,446.

.view. thru the separator adjacent the-rear thereof and showing the feeder, and

Figure 8 is a transverse vertical sectional view thru the thresher showing the grain separator such as illustrated in Figure'2 of my prior Patent 1,392,094, dated Sept. 27th,1921. 1

Referring to the drawings by numeralsof reference, wherein the characters denote like parts thruout the'se'veral figures, 2 indicatesthe frame of the machine, whichmay be of the usual character in general construction and design. v

Arranged transversely within the machine, near the forward portion thereof, on a shaft 4 is a thrashing cylinder 5, said shaft being provided upon each sideof-the machine with lateral extensions 6 and 8 to which may be keyedi or otherwise fixed one or more pulleys 10. whereby the apparatus may be driven by suitable driving belts with the power plantnot necessary to be shown.

Arranged within a casing 12 suitably mounted to one side of the machine, is'a blower fan 14, having a lateral air inlet tube 15 communicatingtherewith, and provided at its lower end'with an outlet communicating with a downwardly and rear-.

wardly inclined air tube 16, at the bottom of which is connected an air chamber18 disposed transversely of said machine.

The air is delivered from the air chamber 18 thru a series ofpassageways 19 into a series of vertically arranged riddles 20 which,

thru a tube 22 open into a chamber 24, con

The chaff and straw from thebottom thereof for the purpose of providing means whereby the suction in the chamber will lift the chaff from the grain through the openings. The chaff thus lifted from the grain will tend to lighten the load and the chaff is then conveyed through the cham- 7 ber 30 and the pipe 44 connected thereto to the stacker of the separator. The suction further, draws the straw thru the pipe or tube 26 from the feeder 25, where it is ultimately delivered thru an air pipe 82 to the stacker pipe as. y y

In Figure 1 ofthe drawings,- 1- haveshown an air and straw deflector 35 which deflects 5 the air and straw downwardly during its movement onto a grain saving device 36 which catches and retains a considerable quantity of kernels of grain heretofore lost. Referring again to Figurefi, I haveshown arranged on the shaft 6, and with the chamber or-casing 12, but separated by a partition 38 from theblower-chamber, a suction fan 40, to which is delivered 'thru an inclined conduit 41, which maybe termed a tailings elevator tube, air :and tailings, which" are delivered ithru tube 42 to the separator.

In Figure 2, 28 indicates the suction fan 'asis'hown in Figure a-andiisidesignedto perform the samecharacter of work, although 2o the straw isnot carried thru the pipe 44 to said fan '28, but by taking up the .air and "chafi from '30 .carriesrthe same by ,pipe 44 to said fan 28, from whence it isde'livere'd bya tube 45 to thestacker tube -46,piclring up the'strawfromthe feeder 4-8 delivered by the feed screw 25.

What I claim as new and-desire to :protest by Letters Patent is:

1. In an'a'ppar'atus'of the class described,

"30 a thrashing cylinder, a blower mounted on the shaft thereof, a seri'esof riddles adapted to receive air from said blower, a tailings elevator, in communication with said riddles, a suction fan for said tailings elevator, on said thrashing cylinder shaft, a straw and chaff elevator tube, a suction fan for said tube on the thrashing cylinder shaft and a straw stacker .tube in communication with said last named suction fan said fan being adaptedto deliver straw to said stacker tube.

2. In an apparatusof the classdescribed, a e thrashing machine frame, a thrashingcylinder journaled 'within said frame, a pair of suction fans arranged on "opposite sides of said machine frame and onsa'id thrashing fiylifide'l shaft, a blower also arranged on said shaft, 1 a casing surroundingsaid blower 1 and 1 one of said fans, a partition separating said blower and said suction fan, .a riddle chamber containing a series=of riddles, an :air chamber rcommunicating "with said :rid-

dies chambenan airtube leading fronrsaid blower to said air chamber, means-of-com- :municationibetween said blower and one of said :suction fans embodying a straw .and chaff elevating tube communicating with the other ofsaid suction fans, a stacker-tube, and a tubeleading from said last :named suction fan to said stacker'tube.

Iii-testimony whereof I affix my signature. WILLIAM ,E. EOILER.
